AIR-PORT.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed November 15, 1913. Serial No. 801,302.

To all whom it may concern:

Be it known that I, ARTHUR J. COUGHTRY, a citizen of the United States, and a resident of Quincy, in the county of Norfolk and State of Massachusetts, have invented a certain new and useful Air-Port, of which the following is a specification.

This invention has for its object the production of a ship air port or port hole, which is particularly simple in construction and highly efficient and durable in use, one of the principal objects being constructions whereby the light frame can be clamped on all sides equally against the packing ring or gasket inserted between the light frame and the sill; and the invention consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is an elevation, partly broken away, of a preferable embodiment of this air port. Fig. 2 is a sectional view on line AA, Fig. 1. Figs. 3 and 4 are enlarged sectional views on lines BB and C-G,

Fig. 1.

This air port comprises, generally, a sill, a light frame hinged to the sill, and means for clamping the frame along its edge against the yielding gasket arranged in a groove in the sill.

1 is the sill arranged to be secured to the side or hull 2 of the ship, the sill having a ring or annular flange 3 adapted to fit a circular hole in the hull.

4: is the annular light frame suitably constructed to hold the pane of glass 5, and 6 is the gasket in a suitable groove in the sill 1 in position to be engaged by the inner circular edge 7 of the frame l. The sill 1 is also formed with hinge leaves 8 and the light frame is also formed with hinge leaves 9 which are pivoted or hinged to the leaves 8 by hinge pins 10. These hinge pins 10 have axially alined spindles upon which the hinge leaves 9 are mounted, and outwardly extending inclined studs 11 movable in converging bearings 12 in the hinge leaves 8, said bearings converging inwardly toward the sill. The hinge pins are moved axially in order to move the studs 11 along their inclined bearings 12 and thus lower, that is, move the axially alined spindles toward the sill l in order that a portion of the edge 7 may be caused to fit more tightly the gasket 6.

The hinge pins 10 are operated by a member, common to both of said pins, here shown as a cam lever 13 pivoted at 14 to a post 15 r sing from the sill 1 midway between the hlnge leaves 8, the cam lever having opposite cams 16 extending eccentrically around the axis 14: and having a sliding engagement with the alined portions of the hinge pins 10.

Other means are provided for clamping the light frame toward and from the sill 1, said means acting on the portion of the frame farthest removed from the hinge and on opposite sides of a line passing centrally of the frame at a right angleto the axis thereof. Said means consists of members in the form of bolts 17 slidable in guides 18 on the sill 1 and having means coacting with the frame 1, the guides 18 being so arranged that the bolts 17 converge toward each other, an an operating member common to both bolts and connected thereto so that it acts equally and simultaneously on both bolts. As here shown, the bolts 17 are provided with hook shape means 19 which enter eyes 20 on the light frame, the bills of the hooks 19 being usually inclined and entering inclined openings in the eyes so that as said bills move into the eyes, the free edge of the light frame is clamped toward the sill 1 to impress the edge 7 into the gasket 6. The bills of the hooks 19 act as wedges and either the eyes 20 or the bills of the hooks 19 or both may be inclined to efiect the wedging action.

21 is the operating member common to both bolts '17, saidoperating member being disconnected from the sill and having an elliptical cam ring 21 which extends through transverse openings 22 in the converging ends of the bolts and which fu'lcrum on the walls of said openings, so that the operating member 21 moves about a shifting axis located between its fulcrum points. Hence none of the force applied to the lever is transmitted to the bolts 17 through the sill 1 and the entire force of the member 20 is applied equally to the bolts 17. The member 21 includes a handle 24 pivoted at 25 thereto on a pivot extending parallel to the face of the sill or to the direction of movement of the member 21, the handle having a tooth 26 on its lower side coacting with a rack 27 on an extenits sion 28 of the sill, the pivotal movement of the handle being for the purpose of disengaging the tooth 26 from the rack 27. The air port is arranged so that the handle 24: is normally in vertical position and falls by gravity into en agement with the rack 27. The light frame is held open in any suitable manner.

Owing to the arrangement of the clamping bolts 17 and their operating member, the clamping action is effected equally and simultaneously on the frame in one operation of the lever 20, thus insuring equal pressure on the gasket which is usually rubber, and avoiding bending of the frame as in constructions now in use. Owing to the construction of the hinge, vibration or rattling of the light is prevented when the air port is open as the hinge pins are never loose in their bearings, and the hinge is readily adjustable to the wear of the gasket.

Although I have shown and described my invention as applied to air ports, obviously it may be applied to other devices and windows and for the sake of brevity, l have used the term air port and other terms throughout the specification and claims.

What I claim is 1.
